Prediction markets are exchanges where people trade contracts based on the outcomes of future events. Each contract pays $1 if the event happens and $0 if it doesn't. The trading price reflects the crowd's estimated probability — for example, a contract trading at $0.70 implies a 70% chance. Platforms like Polymarket and Kalshi host thousands of active markets on politics, crypto, sports, and more.
Research consistently shows prediction markets outperform polls, pundits, and expert forecasts. A 2024 study found Polymarket's election odds were within 1-2 percentage points of actual outcomes. Because traders risk real money, they're incentivized to seek the best information rather than express wishful thinking — making markets a powerful aggregator of collective intelligence.
To start trading: 1) Choose a platform — Polymarket (international) or Kalshi (US-regulated). 2) Create an account and verify your identity. 3) Deposit funds (USDC for Polymarket, USD for Kalshi). 4) Browse markets, buy Yes or No shares at the current price. If your prediction is correct, you earn $1 per share. You can also sell shares before the event resolves to lock in profits.
Polymarket is the largest prediction market by volume, operates internationally using USDC cryptocurrency, and has no trading fees. Kalshi is a CFTC-regulated exchange available to US residents, accepts USD via bank transfer, and charges a small fee per trade. Polymarket has more markets and liquidity, while Kalshi offers regulatory protection for US-based traders.
Yes — traders profit by buying shares when they believe the market misprices an outcome. If you buy Yes shares at $0.30 (30% implied probability) and the event occurs, you receive $1.00 — a $0.70 profit per share. Professional traders, quant funds, and informed amateurs regularly earn returns. However, like any financial market, there are risks — never trade more than you can afford to lose.
